Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of auxiliary equipment for lithium battery separator production, specifically relating to an online oil scraping device for contact rollers. Background Technology
[0002] Currently, when producing lithium battery separators, many manufacturers use contact rollers and shaping rollers with independent temperature control to press the membrane together when the grade requirements are relatively high, in order to ensure the consistency of membrane thickness in the width direction. This is mainly achieved by high-temperature melt flowing out from the die lip and being cooled and formed into a membrane of a certain thickness by the contact rollers and shaping rollers that are pressed together. The shaping rollers are equipped with an oil removal device, and the contact rollers are equipped with a scraper oil removal device. As a result, after oil removal, the performance of the two sides of the membrane is significantly different, making it difficult to obtain separators with higher quality requirements.
[0003] Currently, the doctor blade is in contact with the contact roller. Since the doctor blade is stationary while the contact roller rotates, the rotation speed of the contact roller is limited in order to ensure the oil scraping effect, and the production speed cannot be increased. Secondly, when the doctor blade is in contact with the contact roller, the doctor blade is stationary while the contact roller rotates. Over time, the wear of the doctor blade will generate dust that will be carried into the film. Utility Model Content
[0004] The purpose of this invention is to provide an online oil scraping device for contact rollers, which aims to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An online oil scraping device for contact rollers includes,
[0007] A casting mechanism includes a base, a contact roller rod rotatably mounted on top of the base, and a shaping roller rod hinged to the outside of the base;
[0008] The oil scraping mechanism includes a mounting bracket fixedly installed on the top of the base, a first rotating shaft rotatably installed on the outside of the mounting bracket, a scraper rotatably installed on the end of the first rotating shaft, and a swing arm rotatably installed on the outside of the scraper.
[0009] And the pressure roller mechanism used in conjunction with the casting mechanism.
[0010] As a preferred embodiment of the present invention, the casting mechanism further includes a die head placed on top of the contact roller and the shaping roller, and a fixed seat fixedly installed on top of the base.
[0011] As a preferred embodiment of the present invention, the oil scraping mechanism further includes a second rotating shaft rotatably mounted on the outside of the swing arm, a locking seat rotatably mounted on the end of the second rotating shaft, and a handle fixedly mounted on the outside of the locking seat.
[0012] As a preferred embodiment of this utility model, the pressure roller mechanism includes a positioning plate fixedly installed on the top of the base, a support seat fixedly installed on the outside of the positioning plate, a cylinder hinged to the outside of the support seat, a movable arm rotatably installed at the end of the cylinder, and a connecting beam rotatably installed on the outside of the movable arm.
[0013] As a preferred embodiment of the present invention, the pressure roller mechanism further includes a rotating shaft rotatably mounted on the outside of the connecting crossbeam, a pressure roller rod fixedly mounted on the top of the rotating shaft, and a driving component disposed at the end of the pressure roller rod.
[0014] As a preferred embodiment of this utility model, the driving component includes a motor fixedly mounted on the outside of the positioning plate, an output shaft fixedly mounted on the output end of the motor, and a gear fixedly mounted on the outside of the output shaft.
[0015] In a preferred embodiment of this utility model, there are two cylinders, which are evenly distributed on both sides of the top of the positioning plate, and the gear meshes with the tooth groove at one end of the pressure roller rod.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: the pressure and speed can be adjusted by the pressure roller rod, and a certain speed difference is maintained with the contact roller rod to scrape oil, thereby effectively reducing wear. At the same time, while ensuring the oil scraping effect, the production line speed can be increased. Moreover, a certain gap is maintained between the scraper and the contact roller rod, which on the one hand, will not cause wear, thereby avoiding the generation of dust and other products that contaminate the film; on the other hand, the scraper can effectively remove larger oil films in advance, thereby reducing the workload of the pressure roller rod and improving the oil scraping effect.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0028] Example
[0029] Reference Figures 1-6 This is an embodiment of the present invention, which provides an online oil scraping device for a contact roller, comprising:
[0030] The casting mechanism 100 includes a base 101, a contact roller 102 rotatably mounted on the top of the base 101, and a shaping roller 103 hinged to the outside of the base 101.
[0031] The oil scraping mechanism 200 includes a mounting bracket 201 fixedly mounted on the top of the base 101, a first rotating shaft 202 rotatably mounted on the outside of the mounting bracket 201, a scraper 203 rotatably mounted on the end of the first rotating shaft 202, and a swing arm 204 rotatably mounted on the outside of the scraper 203.
[0032] And a pressure roller mechanism 300 used in conjunction with the casting mechanism 100.
[0033] The casting mechanism 100 includes a base 101, a contact roller 102, a shaping roller 103, a die head 104, and a fixed seat 105. High-temperature melt flows out from the lip of the die head 104 and is cooled and formed into a diaphragm of a certain thickness by the contact roller 102 and the shaping roller 103 pressing against each other. At the same time, an oil scraping mechanism 200 and a pressure roller mechanism 300 are equipped to work together. Through reasonable structural design and coordination of various mechanisms, the diaphragm can be processed more evenly during the diaphragm production process, avoiding the problem of large differences in performance on both sides of the diaphragm caused by oil removal after extraction in traditional methods. This helps to obtain diaphragms with higher quality requirements.
[0034] Specifically, the casting mechanism 100 also includes a die head 104 placed on top of the contact roller 102 and the shaping roller 103, and a fixed seat 105 fixedly installed on top of the base 101.
[0035] The die head 104 is used to allow the high-temperature molten material to flow out from the lip, thereby realizing the casting operation.
[0036] Furthermore, the oil scraping mechanism 200 also includes a second rotating shaft 205 rotatably mounted on the outside of the swing arm 204, a locking seat 206 rotatably mounted on the end of the second rotating shaft 205, and a handle 207 fixedly mounted on the outside of the locking seat 206.
[0037] The adjustable nature of the scraper 203 allows for more efficient contact with the contact roller 102, reducing dust generation caused by wear and tear from prolonged use. Furthermore, unlike traditional stationary scrapers, this adjustable design allows the scraper 203 to better adapt to the rotation of the contact roller 102, eliminating restrictions on its speed and increasing production speed. For example, in actual production, the contact roller 102 can operate at a higher speed while the scraper 203 effectively scrapes oil, significantly improving the production efficiency of lithium battery separators.
[0038] Preferably, the pressure roller mechanism 300 includes a positioning plate 301 fixedly mounted on the top of the base 101, a support seat 302 fixedly mounted on the outside of the positioning plate 301, a cylinder 303 hinged to the outside of the support seat 302, a movable arm 304 rotatably mounted on the end of the cylinder 303, and a connecting beam 305 rotatably mounted on the outside of the movable arm 304. The pressure roller mechanism 300 also includes a rotating shaft 306 rotatably mounted on the outside of the connecting beam 305, a pressure roller rod 307 fixedly mounted on the top of the rotating shaft 306, and a driving member 308 disposed at the end of the pressure roller rod 307.
[0039] The stable operation of the pressure roller mechanism 300 and its effective handling of the diaphragm further reduce the risk of dust entering the diaphragm and improve the quality of the diaphragm. The cylinder 303, movable arm 304 and other structures can ensure that the pressure roller 307 applies stable pressure to the diaphragm, making the diaphragm more stable during the production process and reducing the possibility of dust entering the diaphragm due to vibration and other reasons.
[0040] Furthermore, the drive component 308 includes a motor 308a fixedly installed on the outside of the positioning plate 301, an output shaft 308b fixedly installed on the output end of the motor 308a, and a gear 308c fixedly installed on the outside of the output shaft 308b. There are two cylinders 303, which are evenly distributed on both sides of the top of the positioning plate 301. The gear 308c meshes with the tooth groove at one end of the pressure roller rod 307.
[0041] Among them, the motor 308a, output shaft 308b and gear 308c in the drive component 308 work together to make the pressure roller rod 307 work, thereby making reasonable adjustments to the position of the pressure roller rod 307.
[0042] In use, during the production of lithium battery separators, high-temperature melt flows out from the lip of the die head 104 of the casting mechanism 100, and is pressed and cooled by the rotating contact roller 102 and the shaping roller 103 to form a film of a certain thickness.
[0043] In the oil scraping mechanism 200, the first rotating shaft 202 on the mounting support 201 drives the scraper 203, and through the cooperation of the swing arm 204, the second rotating shaft 205, the locking seat 206 and the handle 207, flexible adjustment is achieved to scrape oil from the contact roller 102;
[0044] Meanwhile, in the pressure roller mechanism 300, the cylinder 303 on the outside of the support seat 302 on the positioning plate 301 pushes the movable arm 304, the movable arm 304 drives the connecting beam 305, and the connecting beam 305 causes the pressure roller rod 307 to process the film through the rotating shaft 306. The motor 308a in the driving component 308 drives the pressure roller rod 307 to rotate through the output shaft 308b and the gear 308c. All mechanisms work together to complete the film production and oil scraping process.
[0045] In summary, the contact roller 102 and the shaping roller 103 in the casting mechanism 100 work together with the die head 104 to achieve the cooling and forming of the diaphragm; the scraper 203 in the oil scraping mechanism 200 is multi-dimensionally adjustable through the first rotating shaft 202, the swing arm 204, the second rotating shaft 205, etc., avoiding limiting the rotation speed of the contact roller 102, increasing the production speed, and reducing dust generated by scraper wear; the pressure roller mechanism 300 ensures the stable operation of the pressure roller 307 through the cylinder 303, the movable arm 304, the connecting beam 305, etc., and the motor 308a, the output shaft 308b, and the gear 308c in the drive component 308 work together to make the pressure roller 307 work, further reducing the risk of dust being introduced into the diaphragm, improving the overall diaphragm quality, and helping to obtain diaphragms with higher quality requirements.
